Learn how to implement comprehensive observability strategies for application deployments in this 30-minute conference talk that addresses the common challenge of debugging performance issues when users report "the app is slow." Discover practical solutions for measuring and reducing latency across global regions, tracking down slow rendering issues, API timeouts, and client-server delays through real-world examples from HelloFresh's deployment challenges. Explore techniques for optimizing performance through strategic caching and co-location strategies, while gaining insights into building scalable observability systems that provide end-to-end visibility into application performance from global latency differences to hydration delays and multi-service bottlenecks.
